Operation Manual

Solving Network Connection Problems

• Check the projector's network settings.

• Set DHCP to Off. When DHCP is set to On, it may take some time to

enter LAN standby status if an available DHCP server is not found.

• Set the IP address, the subnet mask, and the gateway address for the

projector correctly.

• Close network settings on the projector, and then return to the LAN

standby screen.

• Check the computer's network settings.

• Enable LAN settings on your computer.

Windows Vista: Check Control Panel > System and Maintenance >

Device Manager.

Windows 7, Windows 8, Windows 8.1, and Windows 10: Check Control

Panel > Hardware and Sound > Device Manager.

• Turn off the firewall. If you do not want to turn it off, register the firewall

as an exception. Make the necessary settings to open the ports. The ports

used by this software are "3620", "3621", and "3629".

• Check the software settings.

• Select the network adapter you are using from Switch LAN on the Set

options screen. If the computer has multiple LAN environments, a

connection cannot be established unless the network adapter is selected

correctly.

• If you cannot find the projector you want to connect to using Automatic

search, select Manual search to specify the IP address.

• Make sure you start the software in the connection mode that you set on

the projector. If you cannot select or change the connection mode, select

Display Connection Mode Selection window on startup on the General

settings tab in the Set options screen. The select connection mode screen

is displayed after restarting the software.

• Make sure the projector supports the Epson iProjection version being

used. Install Epson iProjection from the EPSON Projector Software CD-

ROM supplied with the projector (if available) or download it from the

Epson Web site.

• Install the latest version of Epson iProjection on all computers. The

maximum number of computer connections and the availability of the

moderator function varies depending on the projector model, no matter

which version of Epson iProjection you are using.

• When another user is already connected, you can only connect to

projectors in the same mirroring group as that selected by the other user.

Select a projector from the same mirroring group as the user who is

already connected, or select a projector that is in standby status.
